Deuteronomy 12:7, 18

and there ye shall eat before Jehovah your God, and ye shall rejoice in all that ye put your hand unto, ye and your households, wherein Jehovah thy God hath blessed thee.

but thou shalt eat them before Jehovah thy God in the place which Jehovah thy God shall choose, thou, and thy son, and thy daughter, and thy man-servant, and thy maid-servant, and the Levite that is within thy gates: and thou shalt rejoice before Jehovah thy God in all that thou puttest thy hand unto.
